Humidity

Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the naked eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present.

Cave

Caves and caverns are natural voids under the surface of the Earth and have also been observed in other rocky worlds. Caves often form by the weathering of rock and can extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground. Caves which extend farther underground than the opening is wide are called endogene caves.
